MISHNAH. IF THE HIND LEGS OF AN ANIMAL WERE CUT OFF BELOW THE JOINT, IT IS PERMITTED; IF ABOVE THE JOINT, IT IS TREFAH. SO TOO IF THE JUNCTURE OF THE TENDONS WAS GONE, [IT IS TREFAH]. IF THE BONE WAS BROKEN BUT THE GREATER PART OF THE FLESH [AROUND THE FRACTURE] REMAINED, IT IS RENDERED CLEAN BY THE SLAUGHTERING; OTHERWISE IT IS NOT RENDERED CLEAN BY THE SLAUGHTERING. GEMARA. Rab Judah said in the name of Rab who reported it in the name of R. Hiyya, BELOW means below the joint, and ABOVE means above the joint, and the joint referred to is the joint which is sold together with the head. Ulla said in the name of R. Oshaia: It is that joint which is clearly distinguishable in the camel. Ulla said to Rab Judah, ‘According to me, holding as I do that it is that joint which is clearly distinguishable in the camel, it is right that the Mishnah also states: SO, TOO, IF THE JUNCTURE OF THE TENDONS WAS GONE. But according to you, why does it state, SO, TOO, IF THE JUNCTURE OF THE TENDONS WAS GONE?’ — He replied: ‘[It teaches that the animal is trefah] whether the bone was gone and the juncture of the tendons remained, or the juncture of the tendons was gone and the bone remained’. ‘But the Mishnah expressly states WERE CUT OFF’? — He [Rab Judah] was silent [and did not reply]. But when he [Ulla] had left, Rab Judah said to himself, ‘Why did I not answer him thus: BELOW means below the joint, but ABOVE means above the juncture of the tendons?’ Later he said: ‘And did I not suggest an answer to him? but he retorted that the Mishnah expressly states: WERE CUT OFF. Then to this suggestion, too, [he would have retorted, that] the Mishnah expressly states: ABOVE THE JOINT. R. Papa reported the passage thus: Rab Judah said in the name of Rab who reported it in the name of R. Hiyya, BELOW means below the joint and the juncture of the tendons, and ABOVE means above the joint and the juncture of the tendons. So, too, if the juncture of the tendons was gone [it is trefah]; and the actual joint meant is that [which was referred to in the statement] of Ulla in the name of R. Oshaia. But is it possible to conceive of such a case, namely, that if the limb were cut off higher up the animal would live [and it would be permitted], and if it were cut off lower down the animal would die? — R. Ashi retorted: Are you comparing defects with one other? Amongst the various defects we do not say that this resembles that; for one may cut the animal in one place and it will die and in another place and it will live. And this is the extent of the juncture of the tendons — Rabbah said in the name of R. Ashi, That part with is off the bone. Rabbah son of R. Huna said in the name of R. Ashi: That part which is on the bone. Raba the son of Rabbah son of R. Huna said in the name of R. Assi: That part which is above the heel. A certain Rabbi was sitting before R. Abba and recited: It is that part which is on the heel; whereupon R. Abba said: Pay no attention to him, for thus said Rab Judah: It is that part which the butchers strike; and this corresponds with the view reported by Raba the son of Rabbah son of R. Huna in the name of Rab Judah. Rab Judah said in the name of Samuel: The juncture of the tendons of which the Rabbis spoke, is the place where the tendons converge. And how far does it extend? — A certain Rabbi, whose name was R. Jacob, said: When I was at the school of Rab Judah, he said to us: Accept from me the following ruling which I heard from a great man, that is Samuel, viz., The juncture of the tendons of which they spoke is the place where the tendons converge, and it extends from the place where the tendons converge up to the place where they part. How much is this? — Abaye said: Four finger-breadths in an ox. What is the extent in small cattle? — Abaye said: Where the tendons bulge it is part of the juncture, but not where they are sunken in; where they are hard it is part of the juncture but not where they are soft; where they are large it is part of the juncture but not where they are small; where they are white it is part of the juncture but not where they are not white.ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢ
